This polymer compound is filled with solid lubricants, which are released when the polymer is abraded. The release of lubricants lowers the coefficient of friction and improves the wear-resistance of the polymer.
It is used in machine construction for plain bearings and sliding elements that are long-lasting, maintenance-free, and lubrication-free. The polymer bearings can often replace traditional bronze bearings or metal-backed bearings.
Different base polymers are used, e.g. PA6, PA66, or PEEK, in combination with fibre reinforcements and functional fillers; the compounds are customised for specific applications. There are special compounds for high loads, high temperatures, high speed, or food contact.
The sample is as shown on the picture. You can slide the sample on the shaft to get a feel for its low-friction properties.
